“For the sake of peace, therefore, I did propose a test of compromise, by an acceptance, on the part of the Colonists, of an Act of Parliament which should lay the foundation for the extirpation of the horrid custom of slavery in the New World.… My motion was … simply as an act of compromise and reconciliation; and, as far as it was a legislative act, it was still to have been applied in correcting the laws of slavery in America, which I considered as repugnant to the laws of the realm of England, and to the fundamentals of our Constitution. Such a compromise would at the same time have saved the national honor.”[483]

All gratitude to the hero who at this early day vowed himself to the abolition of slavery! Hartley is among the first of Abolitionists, with hardly a predecessor except Granville Sharp, and in Parliament absolutely the first. Clarkson was at this time fifteen years old, Wilberforce sixteen. Only in 1785 Clarkson obtained the prize for the best Latin essay on the question, “Is it right to make men slaves against their will?”[484] It was not until 1791 that Wilberforce moved for leave to bring in a bill for the abolition of the slave-trade. It is no small honor for one man to have come forward in Parliament as an avowed abolitionist, while at the same time a vindicator of our independence.

Again, on the 15th May, 1777, Hartley pleaded for us:—

“At sea, which has hitherto been our prerogative element, they rise against us at a stupendous rate; and if we cannot return to our old mutual hospitalities towards each other, a very few years will show us a most formidable hostile marine, ready to join hands with any of our enemies.… I will venture to prophesy that the principles of a federal alliance are the only terms of peace that ever will and that ever ought to obtain between the two countries.”[485]

On the 5th of June, three weeks afterwards, the “Parliamentary History” reports briefly:—

“Mr. Hartley went upon the cruelties of slavery, and urged the Board of Trade to take some means of mitigating it. He produced a pair of handcuffs, which he said was a manufacture they were now going to establish.”[486]

Thus again the abolitionist reappeared in the vindicator of our independence. On the 22d June, 1779, he brought forward another formal motion “for reconciliation with America,” and, in the course of a well-considered speech, denounced the ministers for “headstrong and inflexible obstinacy in prosecuting a cruel and destructive American war.”[487] On the 3d December, 1779, in what is called “a very long speech,” he returned to his theme, inveighing against ministers for “the favorite, though wild, Quixote, and impracticable measure of coercing America.”[488] These are only instances.

During this time he maintained relations with Franklin, as appears in the “Diplomatic Correspondence of the Revolution,” all of which attests a desire for peace. In 1778 he arrived at Paris on a confidential errand, especially to confer with Franklin. On this occasion John Adams met him and judged him severely. In 1783 he was appointed a commissioner to sign the Definitive Treaty of Peace.


These things belong to history. Though perhaps not generally known, they are accessible. I have presented them for their intrinsic value and prophetic character, but also as the introduction to an unpublished letter from Hartley, which I received some time ago from an English friend, who has since been called away from important labors. The letter concerns emigration to our country, and the payment of the national debt. The following indorsement explains its character:—
